摘　　要：目的 回顾分析海绵状血管瘤CT、MRI表现,总结术前CT、MRI对海绵状血管瘤眼眶内粘连程度预测价值.方法 收集97例经病理证实的海绵状血管瘤病例,均行CT水平加冠状扫描,MRI水平、冠状、矢状、增强＋压脂扫描,对这些病例的CT、MRI表现及手术中粘连程度进行回顾性分析研究.结果 轻度粘连47例,CT、MRI表现为边界清晰、类圆形肌锥内肿物.中度粘连14例,冠状位肿瘤与视神经边界不清,增强后,后极部可见导血管.重度粘连36例,肿瘤形状不规则或者呈桑椹状,肿瘤充满于眶尖,或者虽然肿瘤与眶尖存在三角区,但肿瘤某一边界存在形状扭曲,增强后,后极部呈毛刺状.结论 CT、MRI表现可以帮助明确诊断及初步确定手术入路、判定粘连程度及手术的风险性.Objective To assess the degree of adhesion of cavernous hemangioma （CH） in orbit by CT and MRI features. Methods The authors retrospectively reviewed CT and MRI findings of 97 patients which confirmed to be CH, compared the adhesion degree of CH with recorded before. Results In 97 patients, 47 had slight adhesion, CT, MRI showed well defined margins and were round to ovoid; 14 had mild adhesion, CT, MRI showed no defined margins between CH and optic nerve or extraocular muscles, in area of contrast enhancement, there were often find emissary vein on posterior of CH. Severe adhesion were observed in 36 patients, CT, MRI showed that orbital apex was full filled with tumor, or if not, CH was out of shape, or there were not defined margins. In area of contrast enhancement, posterior of CH was rough or not so smooth.Conclusions Careful analysis CT and MRI images before operation can lead well estimate adhesion degree of CH.
